TL;DR: This feature article highlights some of the recent advances in the last four years, including the various smart routes to construct rough surfaces, and a lot of chemical modifications which lead to superhydrophobicity.

TL;DR: Thermodynamic study showed that the adsorption was a spontaneous and exothermic process and kinetics followed a pseudo-second-order equation.

TL;DR: The results indicated that the formation rate of (·)OH on the surface of irradiated commercial Degussa P25 (P25) was much higher than that of other semiconductor.

TL;DR: A composite of multi-walled carbon nanotube/tungsten oxide (MWCNT/WO(3)) has been successfully synthesized and exhibits an enhanced photocatalytic activity as compared with WO( 3) and a mechanical mixture of MWCNTs and WO (3).

TL;DR: The adsorption kinetic measurements suggest that the diffusivities of CO(2) and CH(4) on Mg-MOF-74 were comparable to those on zeolite 13X and the pressure-dependent equilibrium selectivity of CO (2) over CH (4) (q(CO2)/q(CH4)) in the M g-MOf-74 adsorbent showed a trend similar to that of zeolites 13X.

TL;DR: The micron-scale GO nanosheets (lateral size) enable them to be easily deposited on porous ceramic membranes during water filtration; making them a promising biocidal material for water disinfection.

TL;DR: Their efficiency as antimicrobial agents increased with the hydrophobicity of the amphiphilic cation being the C(14) homologous the most active compounds.

TL;DR: The biodistribution study in mice showed that the micelles decreased drug uptake by liver and spleen and enhanced drug distribution in lung and brain and suggested that PLGA-PEG-PLGA micells would be a potential carrier for CUR.

TL;DR: This work shows not only the possibility of using CuO clusters as a substitute for noble metals in the photocatalytic H(2)-production but also demonstrates a new way for enhancing hydrogen production activity by quantum size effect.

TL;DR: This is the first report on using this type of ionic liquids based on the bis imide anion and different cations of 1-alkyl-3-methyl-imidazolium in ceria nanoparticle synthesis.

TL;DR: The kinetic results revealed that the pore diffusion process played a key role in adsorption kinetics, which might be attributed to the porous structure of synthesized adsorbents.

TL;DR: Experimental results showed that graphene is an excellent fluoride adsorbent with an adsorption capacity of up to 17.65 mg/g at initial fluoride concentration of 25 mg/L and temperature of 298 K.

TL;DR: Colloidal silver nanoparticles synthesized by reacting aqueous AgNO(3) with Medicago sativa seed exudates under non-photomediated conditions were effective anti-bacterial agents and nanoplates are notably smaller and better faceted compared with those synthesizing by vascular plant extracts previously reported.

TL;DR: A Basic-Stern surface complexation model is developed to model observed zetapotentials, while only considering outer-sphere complexes of ions other than protons and hydroxide, which gives reasonable values for the inner Helmholtz capacitance, in line with the Stern layer thickness estimated from surface diffraction results.

TL;DR: The results confirm the existence of three distinct ion adsorption planes (0-, β-, and d-planes), often assumed in EDL models, but with two important qualifications: (1) the location of the β- andd-planes are independent of ionic strength or ion type and (2) "indifferent electrolyte" ions can occupy all three planes.

TL;DR: Organic-inorganic hybrid of chitosan and nanoclay was chosen to develop a nanomaterial with combine properties of hydrophilicity of an organic polycation and adsorption capacity of inorganic polyanion to remove chromium(VI) from aqueous solution.

TL;DR: The high uptake capability and good stability of the Fe-Zr binary oxide make it a potentially attractive adsorbent for the removal of both As(V) and As(III) from water.

TL;DR: FMBO may be promisingly used to remove Sb from drinking water and wastewater and results indicated that the manganese oxide dominated in oxidation of Sb(III) toSb(V) whereas the iron oxide adsorbed the Sb (III) and SB(V).

TL;DR: Results indicate that novel curcumin-loaded TRC-NPs could be a promising candidate for cancer drug delivery.

TL;DR: A combination of mechanisms including straining, blocking, and DLVO-type forces were involved over the range of solution chemistry and nanoparticle concentrations tested, which resulted in improved removal of TiO(2) nanoparticles via filtration and reliable prediction of transport of these potentially problematic nanoparticles through the subsurface.

TL;DR: The surface charge densities of the silica face surface and the alumina face surface of kaolinite particles, recently determined from surface force measurements using atomic force microscopy, show a distinct dependence on the pH of the system.

TL;DR: An interesting discovery that the CO(2) adsorption and desorption on the adsorbent depend on the amine type of the aminosilica adsorbents is reported.

TL;DR: This paper reviews the adsorption of organics on organoclay based upon organoclays for water purification from recalcitrant organic chemicals.

TL;DR: The surface wettability and the relationship between the mass ratio of modified SiO(2) nanoparticles/PVDF and the CA, SA of electrospun mat apparently indicates that the membrane fabricated has a perfect effect of superhydrophobicity.

TL;DR: The thermodynamic parameters were determined which revealed the feasibility, spontaneity, and endothermic nature of adsorption, suggesting that the second-order model best fits the experimental data.

TL;DR: The results suggest that hydrophobic and rough surfaces are not as important as the surface functional groups resulting from PW conditioning film formation for X. fastidiosa adhesion and biofilm development.

TL;DR: The conclusions drawn from purely theoretical computations match remarkably well with the experimental results.

TL;DR: Quantification of nanotube solubility at these plateaus demonstrated that CTAB is the best surfactant for MWNTs at neutral pH conditions, and both cationic and anionic surfactants were found to be poor dispersing aids for highly acidic solutions while, CTABs remained a good surfactan under strongly basic conditions.

TL;DR: Effective pore expansion of M-MSNs similar to that of analogous mesoporous silica nanoparticles was realized when a proper amount of decane was jointly incorporated with limited amounts of TMB.

TL;DR: A novel procedure was developed for the synthesis of a periodic mesoporous organosilica (PMO), which was used to remove polycyclic aromatic hydrocarbons (PAHs) from aqueous solutions and showed similar behavior regarding kinetics after 24 h of contact between adsorbent and PAHs.
